As Naruto Uzumaki returned aboveground to rest, Shihōin Naraku was left wandering the base alone, searching for any benefits he might find.
And sure enough, before Yamato arrived with two squads of Anbu Ninja, Naraku actually found some useful things.
"So that's how it works."
Looking at the documents in his hands, Naraku wore a satisfied expression.
He had truly found useful information.
What White Zetsu were was already common knowledge.
And they were indeed useful, especially for gathering intelligence.
But when it came to combat, White Zetsu could not be counted on.
Of course, that excluded those few special White Zetsu, who did have some strength.
Most White Zetsu, however, would still collapse at the first blow.
And in the Shinobi World War, the White Zetsu Army would have to face the Allied Shinobi Forces.
Against the Allied Shinobi Forces in particular, with their many methods, they might completely collapse under a single charge from the ninja if they were not enhanced.
So to win the war, strengthening the White Zetsu was essential.
In the original story, Obito Uchiha and Kabuto Yakushi had enhanced the White Zetsu using the cells inside Yamato-in other words, Hashirama cells.
But in reality, there was Akame!
Akame was far stronger than Yamato, and her body contained material from the God Tree.
Naturally, there was no need to explain how much the God Tree could enhance White Zetsu.
But before Akame and Yamato appeared, Obito and Black Zetsu would inevitably have had to conduct a series of experiments to find ways to strengthen the White Zetsu.
That was only natural.
It was just that before Kabuto Yakushi joined them, their work on this task had progressed very slowly.
After all, neither Obito nor Black Zetsu was a ninja skilled at conducting experiments like Orochimaru
